Another way to think of it is, a memory-mapped set of wires that are made too thin, and when read, correspond to ones. If ones are written to that region, they become zeroes every time they are read afterward. This is kind of the reverse of how memory normally works.

- peter_d_sherman 7y agoI think it would be interesting to learn the history of e-fuses as applies to CPU architecture... That is, where/how/when were they invented, what was the first CPU to use them, for what purpose, and which CPU's have used them since that point in time... Maybe I'll post to Ask HN or one of the StackOverflow websites about this in the future...
